Aston One-77: on track
Posted: 28 May 2012
There are 225 sensors on this car, most of them thermo-couples measuring - you guessed it - heat. In the exhaust, at the exit of the engine and into the manifold, then all the way into the catalytic converters, out of them, then down the rest of the pipe. There are more measuring oil temperature in the transmission, both into and out of it, on either side of the cooler and on all of the water coolers and within the aircon system and cabin. There are 25 sensors on the body structure alone, more on the suspension and chassis, and still more on heat shields in critical places, where sensors are required on either side of a shield to make sure it's doing its job.
